1'0 (056 whom it may concern.-

Be it known that we, HENRY BRIGGS and Cnnrs'rran DANCEL, citizens of the United States of America, and residents of the city, county, and State of New York, have invented certain new and useful Improvements in Rough-Rounding and Channeling Machines, of which the following is a specification.

Our invention relates to mechanism to antomatically adjust the oscillating cuttingblade or rough-rounding knife and to automatically support and adjust the soles of boots and shoes while they are being roughrounded and channeled and is an improvement upon the machine shown and described in United States Letters-Patent No. 163,967 to Henry Briggs.

The object of our invention is, first to provide means for automatically regulating the length of the stroke of the cutting blade during the operation of rough-rounding a boot or shoe so that whatever the variation in the thickness of the sole may be it shall sever the well; and sole without passing completely through and beyond the throat-plate and gage to mar or cut the upper; second, to provide means for moving the work supportlaterally whenever the channeling-knife is moved laterally, and for moving it the same distance that the channeling-knife is moved, whereby the work support is kept near to and at a constant distance from the channeling-knife; third, to provide two work supports which are free to move vertically, but which are so connected each to the other that when one rises the other descends the same distance, and which are placed one ateach side of the channeling-knife, whereby the knife is made to cut a channel of uniform depth regardless of the position in which the work is held, and whatever may be the irregularities in the thickness of the work.

Figure 1 shows a front elevation of our improvements as in operation, with the feed clamp 1 forward (toward A), and the four-motion drop-feed 45 also forward toward A. Fig. 2 represents a transverse vertical section at GH of Fig. 1, looking from B toward A of Fig. 1, and showing our automatic oscillating cutting-blade adjustment, thesolid linesshowing the feed-clamp 1 as pressed down on a thin part of the work as the shank, the edge-trimming or oscillating cutting-blade 89 being in operation, the dotted lines showing the feed-clamp 1 when raised by agreater thickness of the sole, as in the forepart, at the same time automatically changing the length of the stroke of the oscillating cutting-blade 89 to correspond with the change of position of the feed-clamp 1. Fig.3 shows a plan view of Fig. 2; Fig. 4 an enlarged view of part of Fig. 2, showing the automatic adjustment of the feed-clamp 1 and oscillating cutting-blade 89; Fig. 5 an enlarged front elevation of our self adjusting rest or work support; Fig. 6 a side view of Fig. 5,1ookiug from A toward B of Fig. 1. Fig. 7 shows a plan view of Fig. 5; Fig. 8 an enlarged front elevation of our single adjustable rest or worksupport; Fig. 9, front view of upper part of Fig. 8, fitted with a roller support or table; Fig. 10, side view of upper part of Fig. 8,1001:- ing from A toward Bot Fig. 8. Fig. 11 is an enlarged horizontal section through head 116 and hand lever 93, showing a plan view of slide block 78 with its arm 79, cover 95, pivot 77, adjusting screws 96 and 97, vibrating arm 86, channeling knife 72 and carriage 73, bracket 14:0,arms 110 and 138, work support and channeling knife guard 146 and roller 147, So

the groove in the head 116 for slide block 78 being shown by dotted lines. Fig. 12 isa vertical transverse section on the line P, S, Fig. 11, across the slide block 78 and looking from 0 toward D of Figs. 2 and 11. Fig. 13 is an enlarged detail plan view of the slide block 78 with its arm 79; and Fig. lat is a front elevation of the arm 79.

Similar referenceletters and figuresiudicate similar parts throughout the several views.

Our improvements consist of the eccentric 120 or its equivalent, pivoted on the supporting arin 118, and carrying the pivot or fulcrum 23 of the lever 22, which actuates the oscillating cutting-blade carrying segment 8;

andchanneling knife guards 132 and 133, which are carried in a grooved slide-block 138 and its cover 139, being pivoted at or near 'when one of the two parallel supports and channeling knife guards132 and 133 supporting the sole of the shoe is pressed down, the

other will rise to a corresponding height with the cutting edge of the channeling-knife 72 I asa center. These worksup'ports 132 and 133 (also the single work support 146 when the latter is used) incidentally, in combination with the channeling knife 72, secure a uniform I depth of channel in all parts of the sole operated upon, independent of the varyingthickness of the sole and'welt, inasmuch as they I Y vided with a tongue fitted into a groove 145 forma guard before and behind the channel ing knife. The slide-block 138 has an arm 1.38 proof the arm 140 of bracket 140, this bracket 140 being attached to and carried by the arm 79 of slide block 78' which'slide block 78 runs in the groove or race in the head or rigid standard 116 of themachin'e. By this improvement our self ad j ustin g work su pportsand channeling knife guards132and 133 are caused to move inand out with the arm '79, and the channelingknife 72 and its carriage 7 3, whereby the work supportsand channelingknife guards 132 and 133 are kept near the cutting edge of the arm 140 of bracket 140, together with the oblong bolt holes in bracket 140 enable the work supports and channeling knife guards 132 and 133 to be set in any necessary position relative to the channeling-knife 72 and oscillating cutting-blade 89 required by varied styles of work done.

The work support and channeling knife guard provided with a roller 114 is used to regulate the pitch of the shoe in combination with the automatically adjustable work sup ports and channelingknife guard 132 and 133, and may not be required in some classes of work, when it may be dispensed with it desired.

The operation of a machine with these improvements is as follows: The work is inserted in the usual manner by pressing the hand lever 46 backward (toward D) to the position shown by the dotted lines, thus raising the feed-clamp 1, and the throat-plate and gage '15, while the: lock for the feed-clamp (shown in said former patent.) is unlocked, and

blade 89 is down, permitting the work to be inserted between the work supports and channelingknife guards 132,1:33,four-motiou,dropfeed 45, and the throat-plate and gage 15 and feed-clamp 1, until the inseam is against the edges ofthe two latter parts. The hand le ver 46 is then released and forced by the springw toward the solid lines (toward G),

pressing the feed-clamp, 1, and throat-plate and gage 15 against the upper side of the boot 1 or shoe sole and'welt operated on. r The ma chine is'now put in motion,the lock of the clamp-feed 1 and the throat-plate and gage 15 now looks, and the four-motion drop-feed 45 now rises, clamping'the work. The four-motion drop-feed v45 and feed-clamp 1 are next moved forward (from Btoward A as shown by the solid lines) by the feed-motion carrying the work clamped between them from B toward A. The oscillatingcutting-blade 89 now moves upward through the four-motion drop.- feed 45, the sole operated on, and into the opening in the throat-plate and gage l5, separating or rough-rounding the edge of thesole; the length of stroke of the oscillating cuttingbladebeing varied byouri'mproved mechanism .hereinbefore described so as to pass through the sole and welt operated on. -In former machinesof this character,the oscillating cutting-blade89 had a fixed length of stroke, so

that when adjustedin the segment 5 fora maximum thickness of sole, its stroke could not be changedwithoutstopping the machine and readj usting it, and when set for such maximum the sole) when it reached the shank, which might be much thinner, it was liable to penetrate entirely through the throat-plate and gage 15, projecting above the latter and into the upper of the boot or shoe operated on and injuring the latter. If set for the minimum thickness of sole it might not penetrate entirely through the thicker portion of the sole, and so might fail to separate it in places. Our improvements as shown overcome this defect, because by our improved mechanism, when the oscillating cutting-blade 89 is set for the minimum thickness of sole (as in the solid lines Figs. 2, 3 and 4) and the thicker portion of the sole is reached, the feed-clamp 1 and throat-plate and gage 15 will be raised toward the dotted lines, moving the hand lever 46 toward the dotted lines (toward D), which moves the connecting rod 130 and eccentric arm 122 (also toward D), partly revolving the eccentric 117 pivoted on the fulcrum arm 118, thereby raising the pivot 23 of the lever 22 and depressing the other end of the latter with its rack 21, correspondingly depressing the rack into which it engages on the segment .9, toward the dotted lines, raising the cutting end of the oscillating-blade the rough-rounding or oscillating. cutting- 89 with the upward movement of the feedclamp l a nd throat-plate and gage 15, required by the greater thickness of the sole operated on; these movements being reversed when a thinner portion of the sole is again reached. The long sliding pivot 131 or its equivalent permits the feed movement of the hand lever 46 and feed-clamp 1 from A to B and return already described. At the same time the autornat-ically adjusting work supports and channeling knife guards 132 and 133 accommodate themselves to the longitudinal curves of the sole operated on, as shown by the dotted lines in Figs. 5 and 6 at 132 132 133 and 133", as the sole is passed over them; when one is depressed the other will rise to a corresponding height, keeping the sole in the same relative position to the channeling-knife 72, so that the channel shall be cut to the same depth both in the forepart and in the shank of the sole, and also in case the sole is held unevenly longitudinally by the operator. The lock of the feed-clamp l and throatplate and gage 15 next unlocks, the four-motion drop'feed 45 drops, and its backward movement from A toward B takes place, while the throat-plate and gage 15 with the work remain stationary. Next the oscillating cutting-blade 89 drops down, leaving the machine in the position it was in when the work was inserted. The spring :1: presses the hand lever 46, so as to keep the feed-clamp 1 and throat-plate and gage 15 (connected by the pivot 106 as shown in said former patent) pressed down on the upperpart of the sole and automatically adjusts them for any variation in the thickness of the solo operated on. When the machine is started, the vibrating channeling-knife 72 is also put in motion, actuated by the canrwheel h, and continues to operate while the four-motion drop-feed 45, feed-clamp 1 and oscillating cutting-blade 89 are in action, the distance of its channel from the edge of the sole being regulated by moving the hand lever 93. The some movement of the hand lever 93 also regulates the position of the automatically adjustable work supports and channeling knife guards 132 and 133, which are supported by their slide-block 138, bracket 140 attached to arm 7 9 of slideblock 7'8, the pivot 77 passing through arm 79 towhich pivot 77 is attached the vibrating arm 86 which carries the knifaholder or carriage of the channeling-knife 72, so that the worksupports and channeling knife guards 132 and 133 shall be at all times in the same relative position to the channeling-knife 72 and move in and out with it (from O to D and D to O) as may berequired in cutting the channel at a greater or less distance from the edge of the sole operated on. By a repetition of these processes the boot or shoe sole is rough-' rounded and channeled. When the operation is finished on the sole operated on the machine is stopped in the position described when ready to insert the work. The hand lever 46 is then pressed back (toward D),

raising the feed-clamp 1 and throat-platcand gage 15, releasing the sole, which is then removed from the machine which is now ready for the insertion of the next sole to be operated upon.

\Ve have shown and described the cutting blade 89 as oscillating or reciprocating about an axis as this construction is deemed by us the best, but it is obvious that a cutting blade reciprocating in a straight line can be used instead, and in such case the mechanism for communicating to italength of stroke according to the position of the throat-plate would need only such slight modifications as would be apparent to any machinist.

To do not confine ourselves to the use of different forms of work-supports and channeling knife guards or tables, so we have also shown in Figs. 8,, 9 and 10, the grooved slideblock 138 carrying a single work-support and channeling knife guard 146 whose top may be curved or fiat as required by different styles of soles, or may have a roller 147, to reduce the friction of the sole of the shoe passed over it. The form shown in Figs. 8, 9 and 10 being suitable for use when womens high arch shoe soles are to be channeled and rough-rounded. This work-support and channeling knife guard 146, which is attached to the arm 140 of bracket 140 which is attached to and carried by the arm 79 causing the work-support and channeling knife guard 146 to move in and out with the arm 79 and the channeling-knife and its carriage, in the same manner and for the same purposes as the double work supports and channeling knife guards 132 and 133 more in and out with the channeling-knife 72.

The roller 147 may be placed on the front of either the single work support and channeling knife guard 146 (as shown in Figs. 9, 10, and 11) .or the double work support and channeling knife guards 132, 133, as readily understood, or such roller may be placed on the back of the work supports next to the channeling knife 72, as may be preferred for different kinds of work operated on. The work-supports and channeling knife guards 132 and 133 and 146 may also be fitted with rollers 147, as shown in Fig. 9, to reduce the friction of the sole passed over them as previously referred to.
